The original press release is dated: March 2, 2004.

That's 10 months ago.

If this was really real, we should have heard a lot more about it since. I assume that the Phys. Rev. E article came out in March 2004 as well.

Something is not right hear.

However, the idea is interesting. They are using the same basic physics as sonoluminescence. However, the sonoluminesence temperatures were no where near 15 mega Kelvin, closer to 10 kilo Kelvin; about a factor of 1,000 lower.

Thanks. Anyone following it fair-mindedly expected this in due course.

Moving at about the speed of sound, the internal shock waves impacted at the center of the bubbles causing very high compression and accompanying temperatures of about 100 million Kelvin.

Now I'm not too sure about those crazy metric measurements, but I don't think that fusion at a temperature of 100 million Kelvin is best described as cold.

Cool.

Not everyone who appears on "Coast to Coast AM" is a kook.

Apparently, there will also be a consortium:



CORRECTING and REPLACING Consortium Formed to Study Acoustic Fusion; Could be Alternative to Oil, Gas, Coal and Nuclear Power

     CORRECTION...by The Acoustic Fusion Technology Energy Consortium

GRASS VALLEY, Calif.--(BUSINESS WIRE)--Jan. 12, 2005--Sixth graph, first sentence should read xxx Dr. Rusi Taleyarkhan, The Ardent Bement Jr. Professor of Nuclear Engineering, Purdue University, and part-time Distinguished staff at a National Laboratory (sted xxx Dr. Rusi Taleyarkhan, The Ardent Bement Jr. Professor of Nuclear Engineering, Purdue University, and part-time Distinguished staff, Oak Ridge National Laboratory).

The corrected release reads:

CONSORTIUM FORMED TO STUDY ACOUSTIC FUSION; COULD BE ALTERNATIVE TO OIL, GAS, COAL AND NUCLEAR POWER

The Acoustic Fusion Technology Energy Consortium (AFTEC) has been formed by leading academic and commercial institutions to research and develop acoustic inertial confinement fusion (AICF) and its related science, technologies, and equipment. AFTEC's five founders are (alphabetically): Boston University; Impulse Devices, Inc.; Purdue University; University of Mississippi; and University of Washington Center for Industrial and Medical Ultrasound.

Dr. Wylene Dunbar, Director of AFTEC, today announced the group saying, "Acoustic fusion has an excellent chance of becoming the alternative to oil, gas, coal and nuclear energy for the world's electricity -- if it is funded appropriately."

"If AICF delivers on its potential, the impact would be enormous. Fusion could produce electricity with a process that yields virtually no pollution--just ordinary helium and heat," Dr. Dunbar observed. "With acoustic fusion, the fuel is essentially water, and the cost to build and operate a plant would be a fraction of other alternative energy facilities. Furthermore, the timetable for acoustic fusion is arguably far shorter than all other paths to fusion."

In AICF, sound waves bombard a liquid such as heavy water, to create tiny void "bubbles" or "cavities" of deuterium a/k/a heavy hydrogen. This produces very high temperatures and densities that, when high enough, fuse the heavy hydrogen into helium. That fusion releases enormous heat that could be used to create steam and drive a turbine to produce electricity.

An emerging field, acoustic inertial confinement fusion can already lay claim to significant progress: A multi-institution team led by Dr. Rusi Taleyarkhan has twice documented fusion reactions taking place in an AICF reactor, with the results of those seminal experiments published in two prestigious, peer-reviewed journals, Science 295, 1868 (2002) and Physical Review E 69, 036109 (2004), and receiving publicity worldwide. Under the direction of its President, Ross Tessien, Impulse Devices has recently made available the first commercial research reactor for AICF.

Scientists leading AFTEC's research are preeminent in the field: Dr. R. Glynn Holt, Associate Professor, Department of Aerospace/Mechanical Engineering, Boston University; Dr. D. Felipe Gaitan, (discoverer of single-bubble sonoluminescence, a phenomenon closely related to acoustic fusion research), Chief Scientific Officer, Impulse Devices, Inc.; Dr. Rusi Taleyarkhan, The Ardent Bement Jr. Professor of Nuclear Engineering, Purdue University, and part-time Distinguished staff at a National Laboratory; Dr. Henry Bass, Director of the National Center for Physical Acoustics, University of Mississippi, and F.A.P. Barnard Distinguished Professor of Physics & Astronomy; and Dr. Lawrence A. Crum (leading researcher in the field of high intensity focused ultrasound and past president of The Acoustical Society of America) Professor of Bioengineering and Electrical Engineering and Director, Center for Industrial and Medical Ultrasound, Applied Physics Laboratory, University of Washington.

Members of AFTEC will work as a team to investigate acoustic fusion, Dr. Dunbar noted, and will consult with National Laboratory scientists for independent verification of positive results, as they are achieved.

"All of the scientists involved with this research appreciate that acoustic fusion is a relatively new field and one that has, so far, received little funding support," Dr. Dunbar stated. "Nevertheless, given AICF's potential for creating a limitless, nonpolluting source of sustainable energy, as well as myriad other applications, they also agree that the investigation of acoustic fusion is critically important and deserving of high priority."

Dr. Dunbar received her Ph.D. in Philosophy from Vanderbilt University and her J.D. from the University of Mississippi.

Goodbye dependence on Middle East oil. Or any oil. Since they'll have nothing else to sell the world...I don't count their rugs...Islamofascists will be upset. No more income. No more oil cartel. Saudi Arabia had better start reading the tea leaves.

Good News!, but:

“Additional Evidence of Nuclear Emissions During Acoustic Cavitation,”

That happens to me all the time!

Acoustic ICF Technology

Fusion reactions are driven in linear accelerators, cyclotrons, tokamak fusion reactors, laser inertial confinement fusion reactors, and with numerous others approaches. However a fusion technology capable of producing sufficient energy which is economically viable has proven to be an elusive goal.

A cost effective fusion technology is challenging because extremely high temperatures and pressures are required. Fusion reactions only occur at temperature and pressure conditions one finds at the center of a star like our Sun, where indeed these reactions take place.

When hydrogen (or deuterium, also known as heavy hydrogen) is heated to extremely high temperatures, the nuclei of the hydrogen atoms collide and fuse together, producing helium and a large amount of energy. The reaction yields over a million times more energy than the energy required to separate the hydrogen from water. A small part of the mass is lost when the atoms combine, or fuse, to make helium, and the loss in mass gets converted into energy.

Acoustic ICF is a process where ultrasonic energy is used to create violent spherical imploding collapses inside a fluid. IDI's Acoustic ICF technology has the goal to take this process to the extreme temperatures and pressures required to promote fusion reactions. The spherical convergent collapses of the cavities lead to rapid accelerations, and our initial simulations predict resulting plasma temperatures capable of significant fusion yields.

Actually, acheiving fusion isn't that hard. Anyone could build an inertial electrostatic containment device in their garage that would produce a neutron flux indicative of (D-D) fusion.

Of course, you have to put far more energy in than you would get out.

While it is significant that they have verified a form of cold fusion, it does not follow that we are necessarily any closer to fusion as an energy source.

the press release from Rennsaler is dated for spring of 2004. They took their results to the feds last fall along with several others and the Feds looked at their stuff and turned them down.
